This server has critical structural failures. The MCP implementation is not functional. The mcp_server.py file contains only a stub that prints JSON and exits, it does not implement the Model Context Protocol at all. There is no tool handler, no request/response loop, and no actual MCP communication. The single tool 'execute_skill_action' has no visible input schema, no parameters, and an extremely generic description (11 characters). The tool cannot be invoked because the server has no RPC infrastructure to dispatch calls. The client.py and example_usage.py files are standalone Python scripts that do not interact with the MCP server in any way. This is not an MCP server, it is a broken stub with a tool definition that exists only in the rubric metadata, not in actual code.

• Implement a proper MCP STDIO request/response loop in mcp_server.py. Use the official MCP Python SDK or manually parse/emit JSON-RPC 2.0 messages. The current print-and-exit stub is non-functional.
• Define explicit input parameters for 'execute_skill_action' (or rename it to 'synthesize_literature_review'). Each parameter must have a type, description, and constraints (e.g., query: string, max_papers: integer 1-100).
• Document the complete output schema. Example: { literature_review: { summary: string, key_themes: string[], papers_analyzed: integer, references: { title: string, authors: string[], year: integer }[] } }
• Rewrite the tool description to be LLM-optimized (50-200 chars). Example: 'Synthesize an academic literature review from a query. Returns a summary of key findings, identified themes, and cited papers. Use this to understand the state of research on a topic.'
• Add parameter descriptions. Example for 'query': 'Search query describing the research topic (e.g., "transformer attention mechanisms"). 5-200 characters.'
• Integrate client.py logic into the tool handler so the server actually processes requests instead of returning hardcoded results.
• Add error handling. Define what happens if the query is empty, too long, or yields no results. Return structured error responses with recovery guidance.
• Add tool annotations (readOnlyHint: true, idempotentHint: true) to signal that this tool is safe to retry without side effects.
• Consider renaming to 'synthesize_literature_review' or 'search_academic_papers' to be more specific and action-oriented.
